Avery & PennyCooper have six sons, two daughters, thirteen grandsons and nine granddaughters.

Avery always wondered if Penny had an affair that resulted in her pregnancy with Finlay and Zachariah because Finlay is the only one of their kids with black hair and Zachariah is he only one of their kids who doesn't have green eyes but he still loves them as his own and would never confront Penny about it.

The reason so many of the grandkids have Veela hair wand cores is that they're all 1/16 Veela through Penny's maternal grandmother.

Although all four Hogwarts houses are represented fairly evenly within the family, Hufflepuff is the most common.
